Apple iPhone 7 Plus

Troubleshooting

If your device isn't working properly, you can try several solutions to solve the problem. In most cases you can solve the problem by following these guidelines:

I can't turn on my mobile phone

Cause 3 of 10: An incorrect PIN has been entered

The PIN is used to protect your SIM card from unauthorised use. If an incorrect PIN is entered, you can't turn on your mobile phone.

Solution: Key in the correct PIN. If an incorrect PIN is entered three times in a row, your SIM card will be blocked and you need to key in your PUK. The PUK can be obtained by logging on to Swisscom Customer Centre.
